Linux Integration Services v2.1 RTM

leave a comment »

From Virtualization Team Blog

“We are really excited to announce the availability of the Hyper-V Linux Integration Services for Linux Version 2.1. This release marks yet another milestone in providing a comprehensive virtualization platform to our customers. Customers who have a heterogeneous operating system environment desire their virtualization platform to provide support for all operating systems that they have in their datacenters. We have supported Linux as a guest operating system on our virtualization platform from the days of Virtual Server and continue to enhance our support in that regard.”

The following features are included in the 2.1 release:

Driver support for synthetic devices: Linux Integration Services supports the synthetic network controller and the synthetic storage controller that were developed specifically for Hyper-V.
Fastpath Boot Support for Hyper-V: Boot devices take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.
Timesync: The clock inside the virtual machine will remain synchronized with the clock on the host.
Integrated Shutdown: Virtual machines running Linux can be gracefully shut down from either Hyper-V Manager or System Center Virtual Machine Manager.
Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.
Heartbeat: Allows the host to detect whether the guest is running and responsive.
Pluggable Time Source: A pluggable clock source module is included to provide a more accurate time source to the guest.

This version of the integration services for Hyper-V supports Novell SUSE Linux Enterprise Server 10 SP3, SUSE Linux Enterprise Server 11, and Red Hat Enterprise Linux 5.2 / 5.3 / 5.4 / 5.5.
Obtain the Linux IC’s via the Microsoft Download Center.

SCVMM integration with Opsmgr fails with the error ID:10207

leave a comment »

How to recover from the error 10207 when performing the Administrator setup console stage:

Setup was not able to retrieve the service account from the specified Virtual Machine Manager server.
Specify a different VMM server and then try the operation again.

ID: 10207

Check if the SPN for the SCVMM service account is OK. Use the SETSPN -L, or check the account properties using ADSIEDIT or any other tool that allows you to confirm the SPN. If everything is ok you may need to recreate the SCP container that is under the SCVMM server account (In the picture bellow you can check that using the tool ADSIEDIT.msc).

 

To manually create this container, use the SCVMM CD and browse to the \Setup folder using command prompt.  Run CONFIGURESCPTOOL.EXE –INSTALL from that folder.  This should create the SCP, after running the cmd confirm the SCP creation using ADSIEdit.  Now rerun the integration setup and all steps should complete without errors.

Note: If you do uninstall/reinstall SCVMM then make sure you patch it to the level it was at before.  Up-to-date SCVMM agents cannot communicate with out-of-date SCVMM servers.

Microsoft System Center Virtual Machine Manager Self-Service Portal 2.0 Release Candidate

leave a comment »

VMMSSP (also referred to as the self-service portal) is a fully supported, partner-extensible solution built on top of Windows Server 2008 R2, Hyper-V, and System Center VMM. You can use it to pool, allocate, and manage resources to offer infrastructure as a service and to deliver the foundation for a private cloud platform inside your datacenter. VMMSSP includes a pre-built web-based user interface that has sections for both the datacenter managers and the business unit IT consumers, with role-based access control. VMMSSP also includes a dynamic provisioning engine. VMMSSP reduces the time needed to provision infrastructures and their components by offering business unit “on-boarding,” infrastructure request and change management. The VMMSSP package also includes detailed guidance on how to implement VMMSSP inside your environment. 
VMMSSP is not an upgrade to the existing VMM 2008 R2 self-service portal. You can choose to deploy and use one or both self-service portals depending on your requirements.

The self-service portal provides the following features that are exposed through a web-based user interface:

  • Configuration and allocation of datacenter resources: Store management and configuration information related to compute, network and storage resources as assets in the VMMSSP database.
  • Customization of virtual machine actions: Provide a simple web-based interface to extend the default virtual machine actions; for example, you can add scripts that interact with Storage Area Networks for rapid deployment of virtual machines.
  • Business unit on-boarding: Standardized forms and a simple workflow for registering and approving or rejecting business units to enroll in the portal.
  • Infrastructure request and change management: Standardized forms and human-driven workflow that results in reducing the time needed to provision infrastructures in your environment.
  • Self-Service provisioning: Supports bulk creation of virtual machines on provisioned infrastructure through the web-based interface.Helps business units to manage their virtual machines based on delegated roles.

KB982501:The monitoring of SNMP devices may stop intermittently in System Center Operations Manager or in System Center Essentials

KB982501:The monitoring of SNMP devices may stop intermittently in System Center Operations Manager or in System Center Essentials

When you monitor some Simple Network Management Protocol (SNMP) devices by using System Center Operations Manager or System Center Essentials, the monitoring may stop intermittently. This issue affects the SNMP performance collection rules or the SNMP event monitors.

After you restart the OpsMgr Health service or the System Center Management service on the proxy agent, the monitoring of the SNMP devices continues as usual for a while. However, this issue may again occur sometime later. 

Additionally, the following event is logged in the Operations Manager log when this issue occurs:

Source: HealthService
Date: date
Event ID: 4000
Task Category: Health Service
Level: Error
Keywords: Classic
User: N/A
Computer: computer name
Description:
A monitoring host is unresponsive or has crashed. The status code for the host failure was 2164195371.
